Hemifacial spasm. Occurrence in multiple sclerosis.

We present six patients with hemifacial spasm and multiple sclerosis. To our knowledge, this association has not been described previously in the North American literature. Magnetic resonance imaging was obtained in all the patients and plaques consistent with multiple sclerosis were identified. In two patients the plaques were seen in the area of the facial nucleus on the involved side. We suggest that hemifacial spasm can be a manifestation of multiple sclerosis. These cases illustrate the utility of magnetic resonance imaging in the investigation of hemifacial spasm. Our findings also support a central (nuclear) origin in multiple sclerosis associated with hemifacial spasm.

Central neurofibromatosis: a clinical-pathological correlation.

Central neurofibromatosis is a genetic disorder of neural crest tissue derivatives that includes bilateral acoustic neuromas and other central nervous system tumors, usually meningiomas or gliomas. This is different from peripheral neurofibromatosis because of the primary central nervous system manifestations and frequent lack of accompanying peripheral neurofibromas and café au lait spots as well as different alterations of nerve growth factor. We present the temporal bone histopathology of a unique case of unsuspected central neurofibromatosis that included bilateral acoustic neuromas invading the cochlea and an asymptomatic glioblastoma multiforme occurring in the absence of a family history and without any accompanying peripheral stigmata of neurofibromatosis. As bilateral tumors frequently invade the cochlea, the modified transotic rather than the translabyrinthine approach is recommended for complete tumor removal. Contralateral tumor removal should be delayed while useful hearing remains.

Atypical osteomyelitis of the skull base.

Most cases of osteomyelitis of the skull base occur as a result of inadequately treated localized malignant otitis externa. We present four patients with osteomyelitis of the skull base who did not present initially as malignant otitis externa. Increased morbidity may occur when these atypical cases are not promptly recognized and treated.
